A patient calls the office to tell you that his or her urine has changed orange in color. The best response of the nurse is which of the following?

Choice A reason: Cranberry juice typically causes pink or reddish urine, not orange. Orange urine is more commonly linked to medications, dehydration, or liver issues. Asking about cranberry juice is less relevant, as it does not directly address the most likely causes of orange discoloration. Choice B reason: Medications like rifampin, phenazopyridine, or certain vitamins (e.g., B vitamins) can cause orange urine due to their pigments or metabolites excreted renally. Inquiring about new medications is a targeted approach to identify a common, benign cause before escalating to invasive diagnostics. Choice C reason: Immediately scheduling an appointment assumes a serious condition without exploring benign causes like medications or dehydration. This response may cause unnecessary alarm and overlooks a systematic assessment, which could resolve the issue through history-taking alone. Choice D reason: Blood in urine (hematuria) typically causes red or brown discoloration, not orange. Asking about blood is less relevant to orange urine and may confuse the patient, as it does not align with the reported symptom’s likely etiology.
